Pad-steam method of dyeing Nitron with cationic dyes

Pad-steam method of dyeing Nitron with cationic dyes. Murovyakina, L. P.; Vinogradova, O. B. (Ivanov. Khim.-Tekhnol. Inst., Ivanovo, USSR). Izv. Vyssh. Uchebn. Zaved., Tekhnol. Tekst. Prom-sti., (1), 67-71 (Russian) 1977.In this article, certain chemicals are used. Some of their cas registry numbers are 13473-90-0 and 108-46-3 CODEN: IVTTAF. DOCUMENT TYPE: Journal CA Section: 39 (Textiles) A technol. procedure is developed for pad-steam treatment in dyeing of Nitron fibers with cationic dyes using dye solns. contg. inorg. salts and resorcinol [108-46-3] as activator and stabilizer, resp. The optimal dye bath temp. was 25-35.degree.. The highest activation of dye sorption on Nitron fibers was obtained with Ba(NO3)2 [10022-31-8] and Al(NO3)3 [13473-90-0]. The optimum dyeing conditions were: a 10 s impregnation of the fibers, at 25-35.degree., with a soln. contg. dye 1-5, activator 2.5-10, and stabilizer 25-50 g/L, and a 20-40 min steaming at 98-100.degree.. .
